SISTER-HOOK.

T 0 all whom it may concern:

Be it known that I, Lnvwooo E. FOSTER, a citizen of the United States,residing at Hoquiam, in the county of Chehalis and State of \Vashington,have invented a new and useful Sister-Hook, of which the fol lowing is aspecification.

It is the object of this invention to provide a sisterhook, thecomponent elements of which may be united in a novel and improvedmanner.

Another object of the invention is to provide a sister hook, one of thecomponent elements of which is provided with outstanding arms, adaptedto receive the other constituent element of the hook, the constructionbeing such that the last named element will be held between the arms,both against rotation, and against movement transversely of the saidarms; another object of the invention is to provide a novel meanswhereby the element which is engaged between the arms of its fellow, maybe retained therein.

In the drawings,-Figure l is a side elevation; Fig. 2 is an edgeelevation; and Fig. 3 is a transverse section on the line A B of Fig. 1.

In carrying out the invention, two hooks are provided, the same beingdenoted by the numerals 1 and 2, respectively. The hook 1 is provided,intermediate 1ts ends, with parallel, transversely disposed, outstandingarms 4. The hooks 1 and 2 are adapted to cooperate to form an eye 8, andthe portions of the hooks which thus cooperate are beveled, as denotedby the numeral 3, to form a compact structure. That portion of the hook2 which is adapted to be mounted between the arms is rendered polygonal,as denoted by the numeral 5, so as to fit between the said arms moreclosely and against rotation.

The arms 4 are prolonged beyond the polygonal portion 5 of the hook 2,and are provided, in their prolongations, with openings, through which asecuring element, such as a cotter pin 6 or the like may be thrust. Theupper ends of the hooks 1 and 2 are provided with cooperating eyes 7,adapted to receive a line.

It is to be noted that the eye 7 of the hook 2 outstands beyond theadjacent faces of the arms 4. Thus, when the said hook 2 is mountedbetween the arms 4, the eye 7 of Specification of Letters Patent.

the hook 2 constitutes a means for limiting the movement of the hook 2transversely of the arms 4. By reason of the fact that the hook 2 isprovided with a polygonal portion 5, the said hook will be preventedfrom rotating between the arms 1, and thus, the mating portions of thehooks 1 and 2 which cooperate to form the eye 8, will be held closelytogether. hen a rope is passed through the eyes 7, it will be seen thatthe two hooks 1 and 2 are held together, so that the hook 2 cannot slipout from between the arms 4; and in this connection, it may be stated,that, although the employment of the cotter pin (3 is desirable, it isby no means necessary, since the rope which is passed through the eyes7, will serve to hold the two hooks together.

The device is capable of many applications which will readily suggestthemselves to the lumbermen and rigger.

The device is simple in construction, and it will be seen that althoughthe constituent elements thereof may readily be separated, they are soconstructed nevertheless, that they may be readily united, and whenunited, will retain their positions, until manipulated with a deliberateattempt to separate them.

Having thus described the invention,what is claimed is 1. A device ofthe class described comprising two disconnected, frcely separable hooks,adapted to be united to form an eye, one of the hooks having spaced,outstanding arms, between which the other hook may be slid, that portionof the hook which is disposed between the arms being polygonal toregister closely between the arms; the hooks having cooperating elementsto receive a line.

2. A device of the class described comprising two disconnected, freelyseparable hooks, adapted to be united to form an eye, one of the hookshaving spaced, outstanding arms, between which the other hook may heslid; the hooks having cotiperating line-receiving eyes, the eye of thelast named hook being adapted to engage the arms to limit the movementof said hook transversely of the arms.

3. A device of the class described comprising two disconnected, freelyseparable hooks, adapted to be united to form an eye, one of the hookshaving spaced outstanding arms between Which the other hook may be myown, I have hereto afiixed my signature slid, the arms being prolongedbeyond the in the presence of tWo Witnesses.
